![]() In a relatively short period of time 4D ultrasound stimulated multicentric studies on fetal and even embryonic behaviour with more convincing imaging than conventional 2D ultrasound. The most benefits of 4D ultrasound could be real time assessment of fetal face, grimacing, breathing movements, swallowing, mouthing, isolated eye-blinking and reveals the direction of the limbs. In comparison with 2D ultrasound, 4D ultrasound offers real benefits for fetus's assessment prenatal condition. 4D ultrasound allows visualization of embryonic movements two weeks earlier than 2D ultrasound ( 1). In the last few decades, the development of new ultrasound techniques has allowed direct visualization of the fetus in utero ( 1, 2).ĤD ultrasound has recently been introduced in medical practice and complements 2D and 3D examination by obtaining images in real time. In the past, registration of fetal movements and fetal heart rate auscultation were the only methods of the follow-up of fetal well being. This can make the difference between normal and abnormal brain development and may be used for early diagnosis of neurological disorders that become manifest in perinatal and postnatal periods. Results: After 15-20 minutes 4D ultrasound examination, we found a pattern of fetal behavior for each trimester of pregnancy.Ĭonclusions: Dynamic evaluation of fetal behavior reflects directly the processes of maturation and development of the central nervous system. The analyzed parameters for each trimester of pregnancy can be used for performing antenatal neurodevelopment test, used the first time by Professor Kurjak. For the first trimester of pregnancy we assessed eight types of fetal movements and for the second and third trimesters 14 types of fetal movements and facial expressions. Material and Method: The study group included 144 healthy pregnant women with single pregnancies between 7-38 weeks of gestation. The assessment of fetal behavior by 4D ultrasound could allow distinction between normal and abnormal fetal behavior patterns which might make possible the early recognition of fetal brain impairment.Īim: Assessment of fetal movements throughout the pregnancy using 4D ultrasound. Analysis of the dynamics of the fetal behavior with morphological studies has lead to the conclusion that fetal behavior patterns are directly reflecting development and maturation of the central nervous system. The morphology scan is the last routine scan in pregnancy for a lot of women, so let’s make it count.Fetal behavior is defined as any fetal action seen by the mother or fetus diagnosed by objective methods such as cardiotocography (CTG) or ultrasound. At 18 weeks your baby is approximately 14 cm from the tip of the head to its bottom. There is a significant amount of growth and development even over the next week. The health of your baby is important to us We would recommend waiting a couple of weeks before having your morphology scan. ![]() Some women want to have their second trimester or morphology scan as early as possible and are keen to come in at 17 weeks. If your last scan was in the first trimester, it has been a long time since you have seen your baby with ultrasound and you are probably anxious so know that everything is progressing normally. Looking ahead to your morphology scanĪlthough your baby has had some major growth since the first trimester anatomy scan, it can be tricky to see all the fine details at 17 weeks. We recommend the morphology scan is best done at around 19-20 weeks. If you haven’t already, now is also a good time to organise your anatomy or morphology scan. Now is definitely the time to choose which hospital you will deliver at and to book in and complete your first visit. Check list at 17 weeksĪt this stage of the pregnancy, you may have told your friends and family that you are expecting. Again, don’t be concerned if you don’t feel your baby move yet. ![]() If you are in your second or subsequent pregnancy, some women may also start to feel the flicker of movements. Don’t worry too much if you aren’t showing all that much, often first times mums don’t show until much later. By 17 weeks, your uterus has grown so much it will be just below the level of your belly button and you may be starting to show! Some very slim women, or women in the second and subsequent pregnancies may be starting to develop a tummy bump, which may be more pronounced in the evening.
